States' change in claims cost in health overhaul

Medical claims costs are the main driver of health insurance premiums. A study by the Society of Actuaries estimates the new federal health care law will raise claims costs nationally by an average of 32 percent per person in the individual health insurance market by 2017. That's partly due to sicker people joining the pool. The study finds wide disparities among states. The estimates assume every state will expand its Medicaid program.
